Biography

I am Professor of Materials Modelling in the at the University of 糖心TV, where I am also currently serving as Research Cluster Leader for the Predictive Modelling research cluster. I also direct the EPSRC Centre for Doctoral Training in Modelling of Heterogeneous Systems (HetSys) and the (WCPM) university research centre.

Research Interests

Stress concentration at crack tipI develop algorithms and the that implements them, with a particular focus on and approaches, and on quantifying the uncertainty in the output of and . I am also active in applying parameter-free modelling techniques to make quantitative predictions of "chemomechanical" materials failure processes where stress and chemistry are tightly coupled, e.g. near the tip of a propagating crack (left), where local bond-breaking chemistry is driven by long-range stress fields. Prominent examples include:

  • QM-accurate modelling of dislocations. Combining a quantum mechanical description of dislocation cores with an interatomic potential to capture long-range elastic relaxation allowed us to investigate and such as hydrogen (upper right, with tungsten atoms red, green and blue, hydrogen impurity purple and dislocation core and glide path red).
  • Machine Learning a General Purpose Interatomic Potential for Silicon. Albert Bart贸k-P谩rtay, Noam Bernstein and G谩bor Cs谩nyi and I created a data-driven potential for silicon using the (GAP) framework. Our model, published in , is capable of accurately describing its behaviour across a wide range of temperature and pressures, and it comes along with uncertainty estimates that help estimate where it risks straying outside its domain of applicability (right, near a crack tip on the (111) cleavage plane, where uncertainty highest on red atoms).
  • Scattering of cracks by individual atomic-scale impurities. In an article published in , we showed that (e.g. a boron dopant, coloured orange in movie, above right) can be enough to deflect a crack as it travels through a crystal, leading to macroscopically observable surface features (lower right).

Teaching Interests

In 2025/26 I will be teaching in the HetSys CDT and in the MSc in Predictive Modelling and Scientific Computing.
